Multi Cloud is a combination of two or more cloud services from different cloud providers. In-Correct Answers : Private Cloud : The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community Cloud : The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Public Cloud : The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Hybrid Cloud : The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

Infrastructural path involves migrating apps from to Cloud to take advantage of cloud native technologies. Virtual Machine and Bare metal included in the Infrastructural path to migration.

Correct Answer :

DBaaS, sometimes called “managed database service,” is exactly what it sounds like: a service that lets users access and use a database over the cloud, rather than purchasing and setting up their own hardware and software, which they then need to manage themselves.

Explanation

IBM Cloud for VMware Solutions offers Veeam Backup & Replication technology to provide backup, recovery, and replication for your VMware workload on IBM Cloud. To protect your data, use Veeam to create jobs to back up your workload to IBM Cloud Endurance Storage.

Identity and access management, or IAM is used to control access to resources.

Explanation

Block storage, sometimes referred to as block-level storage, is a technology that is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. Developers favor block storage for computing situations where they require fast, efficient, and reliable data transportation.

Explanation

Hypervisor : a hypervisor is a lightweight software layer. A hypervisor is an abstraction layer that abstracts physical compute resources, making them available virtually to virtual machines (VMs). The hypervisor assigns processors, memory, and storage to each VM. It keeps VMs separate so that they do not interfere with each other. Features of a hypervisor are: 1. A hypervisor is software that runs on the physical server or host. 2. It pools the resources from the physical server and allocates them to a virtual environment. 3. Hypervisors are leveraged to virtualize hardware whether it's on-premises or in the public cloud.

Explanation

An advantage for a business to use the pay-as-you-go model is cost savings.

Explanation

Object Storage is suitable for the backup of a database in cloud storage.

Cold Vault (for cold data): Use this option for data accessed only a few times a year. A larger retrieval charge applies for reading data. Common use cases include long-term backup, large data set preservation, or older media content. Cold Vault includes a threshold for object size and storage period with a minimum billable object size of 256 KB and a minimum storage duration of 90 days. Objects smaller than the minimum size will incur a charge for the minimum billable object size. In-Correct Answers : Standard (for active data) : Use this level for active data that's accessed multiple times a month. Your data is immediately available when needed. Common use cases include streaming mobile and web content, DevOps, analytics, collaboration and active content repositories. There are no retrieval charges, no minimum object size and no minimum duration requirement. Vault (for less active data): Use this level for less active data that's accessed once a month or less. Data is immediately available when needed. A low retrieval charge applies for reading data. Common use cases include backup and digital asset retention. Vault includes a threshold for object size and storage period with a minimum billable object size of 128 KB and a minimum storage duration of 30 days. Hot Tier : Hot tier is built in tier type of Smart tier.With Smart Tier, you no longer have to worry about selecting the right storage class for your workloads. Smart Tier will track your monthly activity and bill you one monthly capacity rate from three built-in pricing tiers: hot, cool, or cold. Smart Tier: Smart Tier employs automatic cost optimization to ensure that you get the lowest storage cost each month. This is valuable for all workloads, especially ones with variable or unpredictable data access patterns and ones that change over time.

Hybrid Cloud combines public cloud, private cloud and on-premises infrastructure to create a single, flexible, cost-optimal IT infrastructure. Hybrid Cloud model best suits where security and regulatory compliance required. Use Cases : Security and regulatory compliance: We can reserve sensitive data and highly regulated workloads behind-the firewall in private cloud and can use more economical public cloud resources for less-sensitive workloads and data. Resource optimization, and cost savings: We can manage predictable capacity workload on private cloud and can migrate unpredictable workloads to public cloud to scale up quickly and automatically. Cloud Scaling : A business has on-premise infrastructure that can handle a certain amount of user load. The hybrid allows them to scale up in response to a larger load then automatically de-provision resources when they no longer need them. Multicloud: Composite cloud are applications that are spread across multiple cloud environments. If a business has on-premise architecture that allows them to run three components of their app but the system gets bogged down in busier times, such as holidays, they take advantage of the multicloud architecture by composing their application across multiple cloud environments. In-Correct Answers - Full control over hardware and software choices : In Private cloud, customer have full control over IT infrastructure, They are free to purchase the hardware and software as per their choice. They can customize(configure) servers and software as needed. - Greater visibility into security and access control, In Private Cloud, all workloads run behind the customers’ own firewall. - Greater elasticity and scalability: With public cloud, a customer can add capacity in response to unexpended surges in traffic, without purchasing and installing new hardware. [Exam Tips] : You can expect few questions from here in your exam, so before appearing for exam, you should be aware of use cases of private, public and hybrid cloud.

Explanation

An ACL lists rules that define which source IP addresses can access a particular subnet in a VPC. Access control list rules are prioritized and determined in sequence. ACLs manage ingress and egress traffic for a subnet. It is stateless, meaning that the traffic rules must be specific, separate, and explicit. Each ACL has rules that are based on the following: - Source IP - Source port - Destination IP - Destination port - Protocol Every VPC will have a default ACL to control ingress and egress traffic but by default, all traffic is allowed in and out. These ACLs can be modified or customized and attached to the subnets. A subnet is only able to have one ACL attached to it, but you can attach an ACL to multiple subnets.
